You open a swirling rift of shadow and flame a replica of the fabled Dark Portal. For the duration, the portal pulses with malevolent power. As an action, you or a willing creature can step through the gate to emerge at a predetermined location on another plane. Enemies within 10 feet of the portal when it opens must succeed on a Wisdom saving throw or be Frightened until the end of their next turn. You must have previously visited or seen the destination.
